I have found an old book about GFA and ASM on ATARI ST
i would test a example from the book but it doesn't work well with steem ssE 3.8.0 : glitches
the exemple's goal is make vertical scrolling : modify base address of the video memory
gfa and asm source as attached files.
Steem SEE verion: Steem SSE 3.8.0
some on can test it and give feed back ?
I will check on my real Atari ST soon
